As part of my internship at Me-Mover in Copenhagen I got the assignment to create a luggage carrier for the Me-Mover.

I'll start by explaining what the Me-Mover is. The Me-Mover is a new alternative to folding bikes. It's a 3-wheeled folding vehicle that moves by "stepping" on the pedals.

 

As in all assignments there were a couple of requirements, the main ones being: 
- The ability to carry up to 10kg
- Ensuring the safety of the contents.
- Beeing detachable
- Fitting with the style of the Me-Mover
I started by researching the potential client groups and environments the carrier would be used in and added some custom requirements to the list.
From that point I started brainstorming about different possible concepts and ideas.

Since I wanted to make the carrier as low-key as possible I came up with the following concepts.

Eventually I elected to combine the bottom two concepts.

I eventually chose a concept where there would be one sheet of plastic held into tension by one string of chord.

The thought behind it was that the carrier would hold the contents with enough tension, wether the contents were big or small.

 

To get a better feel for the concept I made some simple cardboard 1/1 models.

This allowed me to see some flaws and some good aspects of the design.

The concept required a flexible material so after some research I opted to use polypropylene for the sheet and a regular elastic cord to hold the sheet in shape.

To test out the materials I recreated the cardboard model with them.

The carrier would slide on a bracket on the bottom and be hooked on the top. The tightening would happen by pulling on the cords and sliding them in a narrowing cut in the plastic sheet.

The second prototype featured a strap to replace the elastic at the top, a more ergonically shaped hook, a "softer" shape and a bracket at the bottom that was designed to be just tight enough for the carrier to slide on it without being to tight or too loose.

As well as metal rings to improve the tightening of the bag.

After some light modifications I made the final presentation prototype with 3D-printed parts and a sheet of polypropylene.

Here are some key points about the "Carry-Me!":

 

- Cheap and easy to manufacture and transport

- A minimum of different materials

- A minimum of parts

- Easy to use (by everyone)

- Fits with the looks of the Me-Mover
